v0.4.0

Hide implementation details around the event queues.

• EventQueue structs are no longer public. All event scheduling must be done through the Simulation structs.
• Event::execute() now takes a &mut Simulation instead of both &mut State and &mut EventQueue.
• Implementations of Debug are overhauled to hide details that client code doesn't control.

v0.3.1

Add new methods to schedule events, supporting "make this happen now" and "make this happen after a set delay" semantics.

v0.3.0

Deduplicate the SimTime and SimState traits to simplify the crate's overall API.

v0.2.0

Relaxes trait bounds in the threadsafe mod.

v0.1.0

Initial release to crates.io. Supports two forms of generic simulations, one with fewer requirements on client types and the other with more easily parallelized execution.
